Polymer-based second harmonic generation materials are disclosed, including electric field poled, chromophore-functionalized polyphenylene ethers with second harmonic coefficients (d.sub.33) as high as 65.times.10.sup.-9 esu, Tg.apprxeq.173.degree. C., and with superior temporal stability of the poling-induced chromophore orientation. Procedures for simultaneously poling and diepoxide cross-linking chromophore-functionalized poly(.rho.-hydroxystyrene) are set forth, resulting in a significant im...

Methodologies associated with fabricating aligned nanowire lattices are described. One exemplary method embodiment includes providing a twist wafer bonded thin single crystal semiconductor film and a bulk single crystal substrate of the same material. Periodic non-uniform elastic strains present on the surface of the film control the positions where nanocrystals will form on the film. The strains may be removed via annealing and alloying after the formation of nanocrystal arrays.

A decoder including first and second decoding stages for selecting a codeword near to a given N-tuple r which is a sequence of N real values r.sub.i representing signals. The first stage includes substages associated respectively with sections r.sub.j of N-tuple r, each substage for evaluating distances between multiple sets of possible partial codewords and the section r.sub.j and for selecting a survivor from each of the multiple sets based on the distances. The second stage includes n-1 subst...

The present invention provides adipose-derived stem cells and lattices. In one aspect, the present invention provides a lipo-derived stem cell substantially free of adipocytes and red blood cells and clonal populations of connective tissue stem cells. The cells can be employed, alone or within biologically-compatible compositions, to generate differentiated tissues and structures, both in vivo and in vitro. Additionally, the cells can be expanded and cultured to produce hormones and to provide c...

Pre-shaped wrought-iron rods are placed one beside another in a lattice array, in which node-forming portions of adjacent rods are disclosed close to each other at a plurality of node positions. All node-forming portions at each of said node positions are inserted into a U-shaped strip metal element having an inwardly protruding longitudinal rib. Each of said strip metal elements is joined to said node-forming portions inserted therein by a projection welding operation in which said rib is used ...

The present invention provides adipose-derived stem cells (ADSCs), adipose-derived stem cell-enriched fractions (ADSC-EF) and adipose-derived lattices, alone and combined with the ADSCs of the invention. In one aspect, the present invention provides an ADSC substantially free of adipocytes and red blood cells and clonal populations of connective tissue stem cells. The ADSCs can be employed, alone or within biologically-compatible compositions, to generate differentiated tissues and structures, b...

Systems and techniques are described in which rank-1 lattices are used in computerized image processing, in particular in the context of image synthesis. These include systems and techniques for selection of rank-1 lattices, rasterization on rank-1 lattices, anti-aliasing by rank-1 lattices, and adaptive refinement and filtering by rank-1 lattices.

A bubble storage system includes a closed loop propagation pattern suitable for use with a bubble lattice. The closed loop propagation pattern is folded and contains, for example, segments of a hexagonal lattice connected by 60.degree. turns to obtain a close pack bubble storage configuration. The bubbles are propagated along the pattern consisting, preferably, of C-bar or chevron type permalloy elements by a rotating magnetic field in the plane of the pattern. In a preferred embodiment, the fol...

A laminar structure upon a substrate is formed from a) a lattice layer comprising DNA (deoxyribonucleic acid) segments arranged to form cells of the lattice layer, and b), at least one nanoparticle being disposed within each cell of the lattice layer. The nanoparticles are preferably of substantially uniform diameter not exceeding 50 nanometers. A coating may be applied to adhere the particles to the substrate and to maintain their substantially uniform spaced-apart relationship. The DNA lattice...

The invention is a film having a discontinuous phase of open and closed cells and a continuous organic phase comprising: (a) one or more block copolymer(s) corresponding to the Formula I: wherein each A is a polymer block derived comprising one or more monovinylidene aromatic monomers, each B is a polymer block derived from one or more conjugated dienes, X is the remnant of a multifunctional coupling agent, m is 0 or 1, and n is an integer from 1 to 5, each A polymer block has a weight average m...
